3. For AIX 5.2 ML1 and later, IBM introduced the dynamic tracking features. The dynamic tracking
defaults to disabled by AIX. The installation adds the required 3PAR ODM attributes for the
dynamic tracking; however, it will not enable it. To enable the dynamic tracking, execute the
/usr/lpp/3PARmpio/bin/3par_dyntrk.sh script.
NOTE:
For an AIX host that will be attached to the 3PAR InServ Storage Server for the first
time, the /usr/lpp/3PARmpio/bin/3par_dyntrk.sh script will not find any 3PAR device.
Therefore no dynamic tracking will be enabled on any adapter. Follow through the rest
of the steps. After reboot, the 3PAR devices are configured and recognized by AIX host.
Run the 3par_dyntrk.sh script at this point. It enables the dynamic tracking on the
adapters that have 3PAR devices attached. Then reboot. The dynamic tracking features
will be active after the reboot. The 3par_dyntrk.sh script also comes with the
-a option, which enables the dynamic tracking features on all adapters.
4. In order to see the 3PAR device(s) from the AIX host, proper port persona on the InServ Storage
Server should be set. Refer to appropriate 3PAR best practice document.
5. Reboot the system.
Post-Installation
To verify the 3PAR MPIO package after reboot, please issue lslpp -l 3PARmpio.64. This command
displays the package level and state. To list the 3PAR MPIO devices, please issue lsdev –Cc disk.
The 3PAR device is described as 3PAR InServ Virtual Volume.
De-Installation
To deinstall the 3PAR MPIO package for IBM AIX:
1. Remove all the devices based on 3PAR VLUNs. For example, rmdev –dl hdiskX, where hdiskX is
a 3PAR InServ Storage Server virtual volume. The following is a sample script to remove all 3PAR
devices:
# for i in $(lsdev -Cc disk |awk '/3PAR InServ Virtual Volume/{print $1}')
# do
# rmdev -dl $i
# done
2. Execute the smit install. Select Software Maintenance and Utilities > Remove Installed
Software. Press F4 to select the 3PARmpio.64. Change the PREVIEW only? to no. Click Enter.
The smit will then deinstall the 3PAR MPIO software. Upon completion, the command status
displays OK.
3. Reboot the system.
